Resumo: The objective of this study was to investigate the behavior of physical attributes and soil carbon stocks in multi-stratified agro forestry system (AFS) compared to different types of land use, including cocoa plantation in agroecological management (CAC), pasture (PAS) and native forest (FLN). The treatments were installed at CEPLAC experimental station in Ouro Preto do Oeste, Rondonia State. Five plots of 20 m x 30 cm were installed at random in each of the four different land use. On those plots, disturbed and undisturbed soil samples in layers of 0 - 20 cm and 20 -40 cm depth were collected for determination of physical attributes and soil carbon stock. Soil density in AFS, CAC and PAS were high and promoted negative influences on soil porosity. Soil carbon stocks were influenced by different land use modality, showing at layer 0 to 20 cm (Mg m-3): 24.79 (ASF); 42.71 (CAC); 41.30 (PAS); 36.07 (FLN), and at layer 20 to 40 cm (Mg m-3): 17.26 (ASF); 31.06 (CAC); 22.31 (PAS); 25.49 (FLN). All evaluated systems presented expected soil carbon stocks, however spatial arrangements that favor the input of organic matter may contribute to increase soil carbon stocks in agroforestry systems.

A área de estudo localiza-se na estação experimental da CEPLAC em Ouro do Preto do Oeste, RO. Nos quatro tratamentos foram instaladas, ao acaso, cinco parcelas de 20 m x 30 m. Nessas parcelas, foram coletadas amostras de solo indeformadas e deformadas nas profundidades de 0 a 20 cm e 20 a 40 cm, para determinação dos atributos fiscos e estoque de carbono no solo. Os valores de densidade do solo no SAF, CAC e PAS apresentaram-se elevados e influenciaram negativamente o espaço poroso do solo. Os estoques de C foram influenciados pelos diferentes agroecossistemas, sendo que na camada de 0 a 20 cm foram de (Mg m-3): 24,79 (SAF); 42,71 (CAC); 41,30 (PAS); 36,07 (FLN), e na camada de 20 a 40 cm foram (Mg m-3): 17,26 (SAF); 31,06 (CAC); 22,31 (PAS); 25,49 (FLN). Todos os sistemas avaliados apresentaram resultados esperados para estoque de C no solo, no entanto, arranjos espaciais que favoreçam o aporte de matéria orgânica poderiam contribuir para a elevação dos estoques de carbono do solo em sistemas agroflorestais.Embrapa Florestas2017-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/129510.4336/2017.pfb.37.89.1295Pesquisa Florestal Brasileira; v. 37 n. 89 (2017): jan./mar.; 19-27Pesquisa Florestal Brasileira; Vol. 37 No. 89 (2017): jan./mar.; 19-271983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1295/552Copyright (c) 2017 Adriano Reis Prazeres Mascarenhas, Marta Silvana Volpato Sccoti, Rafael Rodolfo Melo, Fernando Luíz de Oliveira Corrêa, Emanuel Fernando Maia de Souza, Reginaldo Almeida Andrade, Anderson Cristian Bergamin, Manfred Willy Müllerhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMascarenhas, Adriano Reis PrazeresVolpato Sccoti, Marta SilvanaMelo, Rafael RodolfoCorrêa, Fernando Luíz de Oliveirade Souza, Emanuel Fernando MaiaAndrade, Reginaldo AlmeidaBergamin, Anderson CristianMüller, Manfred Willy2018-01-07T18:59:59Zoai:pfb.cnpf.embrapa.br/pfb:article/1295Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-01-07T18:59:59Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
